EXPERIENCE

    2/2016 - 3/2019: Senior Developer of ESI Mineset, ESI-Group
    8/2014 - 2/2016: Senior Developer of Mineset, SGI
Redesigned legacy 3D native visualizations as 2D versions in a cloud app using Java, Javascript, and libraries like D3, jQuery, Bootstrap, and Backbone. Enabled visualization to work with big data by implementing viz aggregation in Scala on the server using Apache Spark. Replaced legacy MLC++ machine learning algorithms with Apache Spark implementations. Filed patents for pixel perfect rendering of bar charts, and 2D Naive Bayes Visualization. Added support for analysis of time series using SAX and Matrix Profile.

    9/2007 - 8/2014: Technical Lead, PROS, Inc
    3/2006 - 9/2007: Senior Developer, PROS, Inc
Designed and implemented interactive pricing specific charts and reports for the Scientific Analytics product. Some of the custom visualizations implemented in Flex/Actionscript/Javascript were: HeatMap, DemandSensitivity, Waterfall, BandAnalysis, PivotTable, MarginDrivers, and GoalsView. Simplified the creation of UIs for analytics views by producing a generic view editor based on xml configuration. Experience with Hadoop, Impala, Mahout, SaaS, odata4j, D3, gradle.

   10/2004 - 2/2006: Senior Software Engineer, Metreo, Inc
Created interactive pricing specific SVG charts and reports for the Vision product. Built widgets for a dynamic AJAX based Flex-like user interface framework. Used these widgets to construct a deal analysis dashboard that could be embedded in other pricing applications.

    5/2002 - 10/2004: Senior Visualization Engineer, Blue Martini Software
    1/2000 - 5/2002: Manager, Data Visualization, Blue Martini Software
Helped develop several web-based applications including a customer profiler, expression builder, relationship marketing control graph applet, and Java web-start deployed visualization application. My group was responsible for introducing powerful interactive data exploratory tools that could export their results in easy to understand web-deployed reports. Worked closely with the data mining and analytical services group to ensure that our charting components addressed the needs of the customer, and were able to handle specialized e-commerce data. Built the tools in Java taking advantage of third-party libraries from OpenViz and Tom Sawyer. 

    1/1993 - 10/1995: Computer Scientist, Lawrence Livermore National Laboratory
Investigated new techniques for vector field visualization as part of an internal research project. The results have been incorporated into a suite of Iris Explorer modules. Created a class hierarchy of mesh independent visualization algorithms for vector fields.

    7/1990 - 12/1992: Student-Employee, Lawrence Livermore National Laboratory
Developed a method to smoothly transition between bump rendering algorithms so that scale changes during animation would be graceful. Presented a paper and an animation in SIGGRAPH '93.

Developed a collection of frameworks for the creation of simulations, puzzles, and games. Executable versions of these projects are deployed to http://barrybecker4.com/bb4-projects/ and source is at github.com/barrybecker4.
